is there any way to get a servo to rotate to its end point?

I just bought a traxxas 2075 and when I rotate it manually it can rotate 180 degrees, when I use my remote (stock traxxas link 2.4) I can only get it to rotate a max of 90 degrees.

Any way to get it to rotate the full 180? Change gears out perhaps? Thanks

Not sure why you would want to do that?

Standard solution for more travel is a longer servo horn/arm. Will reduce the force it can generate correspondingly of course.
Not so much travel left after +/-45 degrees, well at least assuming a typical set up. Perhaps you are trying to use it differently?
